What is the orange peel phenomenon? A common problem encountered in the polishing process of daily Pet Bottle Preform molds is excessive polishing, which means that the polishing time is long, the mold surface quality is poor, and polishing occurs in two ways: orange peel and hemp. point. So what do we suspect about the orange peel phenomenon? Due to overheating or excessive carburization of the mold surface, excessive polishing pressure and long polishing time are the main reasons for “orange peel”. In the polishing of the light guide plate, the pitting workpiece is often formed by the hard and brittle oxide of steel. Therefore, the cause of pitting is generally high polishing pressure, long time, and rust on the surface of high-purity steel molds. how to solve this problem? a. Carefully grind the surface, the grain size of the sand is cut into the final step of grinding and polishing by a soft and sharp stone that was previously used at a slightly coarser level. b. When the grit size is less than 1 mm, avoid using the softest polishing tool. Use the shortest polishing time and the smallest polishing possible. Since the hardness of the polished workpiece material is too long, two methods can be used to eliminate the orange peel that has been produced: a. In order to remove surface defects, the size of the abrasive grain is slightly rougher than previously used, and then ground to polish some lower dimensions. b. In the stress region where the temperature is lower than the tempering temperature of 25 ° C, the grinding is performed before the finest polishing is used, and finally the lightest polishing strength is achieved. If you want to avoid the above problems, choose a manufacturer with higher visibility and influence is the most direct and effective.
